Method Details

getLastItemSelectedMatrix

public static javax.vecmath.Matrix4d getLastItemSelectedMatrix(SelectedItems selectedItems)

Returns the last selected item's world pose, or null if no items are selected.

Parameters:

selectedItems - the list of selected items

Returns:

the last selected item's world pose, or null if no items are selected.

getPointOnPlaneFromCursor

public static javax.vecmath.Point3d getPointOnPlaneFromCursor(Plane translationPlane,
 Viewport viewport,
 double x,
 double y)

Cast a ray through the camera's viewport at the given x,y and find the intersection point on the translationPlane.

Parameters:

x - the x coordinate of the viewport, in screen coordinates [-1,1]

y - the y coordinate of the viewport, in screen coordinates [-1,1]

Returns:

the point on the translationPlane, or null if no intersection

updateUndoState

public static void updateUndoState(SelectedItems selectedItems)

getPivotMatrix

public static javax.vecmath.Matrix4d getPivotMatrix(FrameOfReference frameOfReference,
 SelectedItems selectedItems,
 Camera camera)

Get the pivot matrix of the selected items. The matrix should be returned in world space.

Parameters:

frameOfReference - the FrameOfReference to use.

selectedItems - the list of selected items

camera - the active camera

Returns:

the pivot matrix of the selected items, in world space. If no items are selected, returns the identity matrix.

listContainsAPose

public static boolean listContainsAPose(List<Node> list)
